NRL players plead not guilty to affray

South Sydney NRL player Dylan Walker and Canterbury recruit Tyrone Phillips have pleaded not guilty to taking part in a violent brawl that left three men in hospital.

The two 19-year-old men fronted Kogarah Local Court on Tuesday where they each pleaded not guilty to a charge of affray over an incident in a car park at Beverly Hills in Sydney's south in the early hours of November 3.

Police have alleged one man suffered puncture wounds to his stomach in the fight, while another was found lying on the ground with a head wound.

A third alleged victim walked away with minor injuries.

After the former South Sydney teammates were arrested, the Bulldogs and Rabbitohs confirmed they were aware of the incident and had advised the NRL Integrity Unit.

"The investigation by the NRL's Integrity Unit is ongoing and the club will fully cooperate with them during this process," South Sydney said in a statement.
